Radius of circle: 5/2*pi m
The answer depends on whether 5m refers to the radius or diameter.
radius = 5 m so circumference = 2*pi*r = 31.4159 m (to 4 dp)
radius = diameter/2 so in this case it would be 2.5 metres.
5m, taking an online math test? Pathetic.
Radius of circle: 5/2*pi m
A radius of 5m means a circumference of 31.4 meters.
Circumference of the circle: 2*pi*5 = 10*pi m
circumference = 2pi5 = 31.416 m rounded to 3 decimal places
The answer depends on whether 5m refers to the radius or diameter.
A circle with a radius of 2.5 meters has an area of 19.63 square meters.
If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.
circumference in m= 5*pi
Multiply the radius by 2, then multiply that result by the value of Pi - and you'll have your answer.
radius = 5 m so circumference = 2*pi*r = 31.4159 m (to 4 dp)
radius = diameter/2 so in this case it would be 2.5 metres.
Use the formula: A = pi x r2. That is, area = pi x radius squared.
